I have to parallel plates with a simple honeycomb in between (basically a sandwich structure). The bottom plat is fixed, the top one moves of a small amount in one in-plane direction. I need to see what happens to the honeycomb in shear buckling. The solution fails to converge. I reduced the time increment to 1e-07 and still I received a message it's not small enough. Shall I just keep decreasing it or is there another strategy I'm not aware of?

Leading manufacturers are aligning their people, processes, and tools from initial product ideation through to field service. They do so by providing access to product and enterprise data in the context of each personâ€™s domain expertise. However, it can be complicated and costly to unite engineering with the factory and supply chain. Download Now
This whitepaper describes the role of thermal transient measurement to characterize semiconductor thermal behavior. It focuses on the value measurement derived structure functions provide through interpretation of the heat flow path inside a package for use in thermal characterization, failure diagnosis, and improving simulation thermal model accuracy.

Itâ€™s easy to fall in love with your own CAD design on the computer screen, but itâ€™s how everything fits together off the screen that really matters. Beyond the design, products need to solve real-life problems or provide huge benefits that genuinely merit separating money from wallets. Download Now
